Find the domain from division of two functions

The video tutorial explains the concept of F of G of X, focusing on understanding its notation and algebraic operations. It discusses the challenges of simplifying expressions, particularly when factoring is not possible. The tutorial emphasizes the importance of identifying domain restrictions by setting the denominator equal to zero and solving for X. It also covers the role of imaginary numbers in determining the domain, concluding that the domain is all real numbers since imaginary numbers do not affect the real graph.
